摘要
对目前火电厂中几种有代表性的高压变频器主电路及输入侧谐波进行了分析,研究其输入侧谐波特性。先从理论的角度进行分析,再通过PSIM仿真软件对其进行仿真,得到其输入侧谐波特性,最后对变频器输入侧谐波电流进行现场测试,测试结果验证了理论分析与仿真的正确性。
The various typical main circuits of high voltage frequency converters and input side harmonics as well as the characteristics are analyzed in the paper.The software PSIM has been utilized for the calculation of the characteristics after the theoretical analysis was carried out.The theoretical analysis and the corresponding numerical calculation are proved to be correct just with the actual data obtained through field tests.
